Alex Karalexis will welcome undefeated Chinese prospect Zhang Tie Quan to the WEC when they square off in a lightweight bout at “WEC 51: Aldo vs. Gamburyan” on September 30 in Broomfield, Colorado, MMAjunkie reports.

Karalexis (10-5) has dropped three of his last four fights, following up a first-round knockout of Greg McIntyre at WEC 39 with a second-round submission loss to Anthony Pettis at April’s WEC 48.

Nicknamed “The Mongolian Wolf,” Quan (11-0) is a veteran of China’s Art of War promotion and has earned first-round stoppages in all 11 of his career bouts, including a 30-second neck crank submission in his most-recent fight in June.
